Do the bonds of the products contain more or less energy than the original compounds?
less
Does butane have more or less H atoms than butene?
More - alkanes in general have more Hs than alkenes An alkane has general formula CNH2N+2 and alkene is CNH2N
What is usually a property of covalently bonded compounds?
Covalent bonded compounds have generally lower melting and boiling points, are not hard, are less conductive etc.
From what classes of elements is the compound made?
Now are known approx. 60 000 000 chemical compounds; all element can form more or less compounds.
What happens to torque when something rotates faster?
When ever you attach a gear with less teeth to a gear with more teeth, thus increasing your gear ratio and the speed in which the gear with less teeth rotate, the amount of torque in your gear combination decreases. This can also be expressed as a ratio, which happens to be the inverse of a gear ratio, meaning if your gear ratio was lets say... 1:5, the ratio for the amount of torque is 5:1, meaning you receive five times less the amount of torque, to increase your speed five times as fast.
What types of product is perfume?
Perfume extract, or simply perfume (extrait): 15-40% (IFRA: typical 20%) aromatic compoundsEsprit de Parfum (ESdP): 15-30% aromatic compounds, a seldom used strength concentration in between EdP and perfumeEau de Parfum (EdP), Parfum de Toilette (PdT): 10-20% (typical ~15%) aromatic compounds, sometimes listed as "eau de perfume" or "millésime." Parfum de Toilette is a less common term that is generally analogous to Eau de Parfum.Eau de Toilette (EdT): 5-15% (typical ~10%) aromatic compoundsEau de Cologne (EdC): Chypre citrus type perfumes with 3-8% (typical ~5%) aromatic compounds. "Original Eau de Cologne" is a registered trademark.Perfume mist: 3-8% aromatic compounds (typical non-alcohol solvent)Splash (EdS) and aftershave: 1-3% aromatic compounds. "EdS" is a registered trademark.
What percentage of aromatic compounds does Eau de Parfum contain?
Sometimes mistaken for the less expensive and lower quality eau de toilette, an eau de parfum has a higher concentration of fragrance. Typically, these types of perfumes will contain 10 to 20 percent aromatic compounds, compared to two to six percent for an eau de toilette.
What are the advantages of Alkanes?
There are a few good advantages of Alkanes. They make great lubricants, are good fuels, and antiseptic for exterior uses.
Why do alkanes get thicker and less runny as the length of the carbon chain increases?
The longer the carbon chain, it spreads out the atoms more equally which causes the carbon to get thicker and less runny.
Are alkanes more dense water?
Alkanes are gases where water is a liquid. therefore the prior is less denser.
What is the similitries between Alkanes Alkenes and Alkynes?
Alkanes have single bonds while Alkenes have double bonds.CnH2n+2 is the general formula for alkanes.CnH2n is the general formula for alkenes.
Why use of alcohol is preferred over mercury in thermometers?
Alcohol is less expensive and the compounds formed from oxides of Mercury are poisonous while alcohol is less problematic.
Why Aniline is less basic then ammonia?
Since aniline N has a lone pair of electrons to dislocate in aromatic system (PI), it has less donating stability then ammonia. Don
Do the bonds of the products contain more or less energy than the original compounds?
less
Why does South have the highest ratio of obesity?
Southerners have the highest ratio of obesity because they are less active
What catalytic converters do to exhaust fumes?
They convert some compounds in the exhaust stream to less harmfull or polluting compounds.
Why polar compounds have less Rf value?
they interact more with the silica gel, thus travel less than non-polar compounds. Resulting in a lower Rf value.
